klonopin help!- newly pregnant

Sash
Hi All-
I am 5.5 weeks pregnant and very excited. That said I have severe vertigo the past year  and the only thing that helps is .5 Mg of klonopin. Since I found out I was pregnant 2 weeks ago I have not taken (and was only taking 1.5 MG max a week) any and it's been hard to even function. Wake up shaky and dizzy and out of it. Has anyone taken these meds and a doctor who was okay with it? Would love some reassurance as I don't want to be miserable for 9 months. Help!
